"The fullest development of the idea about Godship is in Shri Krishna. He reveals Himself to His devotees of different competences in three Forms. All these three are perfect conceptions, not like the partial one of Paramatma and the incomplete one of Brahman. These three perfect conceptions are full, fuller and fullest. These three are revealed in Dwaraka, Mathura and Vrindavana. At Dwaraka Krishna's manifestation is full, at Mathura it is fuller and in Braja (including Vrindavana) it is the fullest."
